The Land Use Structure And Benefit Analysis Of Correlation Between Changes

The land is a non-renewable resources, but also human survival and development ofthe important material base. With the further development of the economic society,the industrialization, the urbanization process of the advance gradually, the scarcity ofland resources supply and demand for the people of the contradiction between theincreasing gradually revealed. In addition, land resources pollution, waste phenomenaexists, further intensifies the shortage of land resources. So find the best of the landresources configuration forms, improve the land intensive use of saving, and realizethe maximization of the land use efficiency is urgent to get people’s attention.In this paper, take Turpan city which is the typical oasis city in Xinjiang as thestudy region, from angles of the principle of using the entropy model of land use for abalanced degree and the advantage degree; On this basis, through Turpan city societyeconomic data analysis, the coefficient of variation of level of comprehensive analysisweighting-that the combination of selection index weight, and then weightedsummation of land use in the study area get economic benefit and social benefit,ecological benefit and comprehensive benefit; Finally, using the grey relation analysis,running in DPS software, it is concluded that the land use structure andcharacterization information entropy value and land use three big benefits andcomprehensive benefit of the correlation between in Turpan city from2000to2009.The analysis results are as follows:(1) Land use structure of information entropy and balanced degrees growthadvantage degree will be reduced from2000to2009. The information entropyincrease from0.2655to0.4363, balanced degree increased to0.2242from0.1364, theadvantage degree reduced to0.7758from0.8636. Show that the study area of land useof the homogeneous strengthens gradually, the land use types tend to be stable,constantly optimize the structure. (2) The land use efficiency increased year after year. Economic benefit and socialbenefit, ecological benefit and integrated benefit all maintained growth trend, theminimum and maximum benefit all appeared in the beginning and the end.(3) The land use structure characterization of information entropy value changewith the change of land use comprehensive benefit highly correlated, and thecorrelation degree reaches0.8755. The information entropy change affect to thecomprehensive benefit of the same direction change.From the correlations of land type and comprehensive benefit: the land usecomprehensive benefit of highly related to class is town village and mining, garden,land for traffic and forest land, correlation degree respectively is:0.8891,0.8847,0.8806and0.8324; Moderate related is land types is the waters, the correlation of0.6386, low related is cultivated land and did not use the land, correlation degree are:the0.5777and0.5381.
